Well, that’s interesting all on it’s own. What chip 2mm square is being used in flashlights with actual (as opposed to eBay, etc. ratings) 200 lumen output? I have higher lumen output flashlights but they use bigger chips, and consequently less tight beams. If I knew what chip to look for, that’d narrow the search for a new head flashlight. :-)
As for the backup bulb, the price is pretty reasonable - $10 for a pair. Higher output bulbs are available but are larger & heavier, which is an issue as those bulbs tend to vibrate out of their sockets if the bulb is horizontal when mounted in the vehicle.
In any event, it’d be nice to find real specs on these 2020 series LED’s.
So these is some kind of packaging standard that all of these fit. Kind of like 2032 or 2025 cell batteries fit a package design.
Well, it is a thought.
